Specification of Letters Patent. Patented June 21, 1921.

Application fuea December 2s, 192e. seran No. 433,600.

` of a calf and to hang down over its mouth so as to frustate efforts of the calf to suck a cow but vwhich will lnot interfere with drinking or grazing, the plate member 'which depends from the mouth being swingableV upwardly in the act of grazing.

An important object is the `provision of a device of this character which includes a pair of separable members engageable within the nostrils of a calf and having a dovetailed connection with each other, these members being locked against separation'by means carried by the plate depending in front of the mouth.

Another' object is the provision of a deV vice of this character in which the nostril engaging members are formed with ring portions through which an operator may insert his thumband first finger forfholding these members in position prior to locking them together byimeans on the plate, the Vdevice entirely avoiding the use of bolts, rivets, cotter pins, or any, other similar fastening devices.

An additional object is the provisionI of a device of this characterl which will be simple andinevxpensive in manufacture, easy to apply even .to arather vicious calf, which will be highly efficient and durable inl use, and a general'improvement in the art.

With vthe above and other objects and advantages in view, the invention consists in the details of construction tov be hereinafter more fully described and claimed and illustrated in the accompanying drawings in whiche Figure 1 is a perspectiveview showing my device in position upon Va calf,

Fig. 2 is a side elevation of the device applied and showing it in the position assumed when the calf is grazing,

Fig. 3 is an elevation of the device on a lar er'scale than that of Fig. l,

ig. 4 is a central cross sectlonal view,

Fig. 5 is a detail cross -sectional view through the nOSe engaging members taken along the hole throughwhich the locking hook passes,

r ig. 6 isa similar view taken above the line of nig. 4, and

Fig. 7 is a perspective view of the nose engaging members separated. Y

Referring more particularly to the drawings, I have shown my device as comprising Va nose engaging portion designated broadly by the numeral 10, and a guard plate 11. This nose engaging portion is formed of two sections 12 which are readily separable and Veach of which includes a hook 13 having a knob-like end lll for engagement within the nostril of av calf. Formed integrally with the lower end of the hook portion is a rectangular plate 15 which is of only onehalf the thickness of the hook portion, as clearly shown, so that when the two sections vare properly assembled the sides of the plate portion 15 will be flush with the sides of the hook. These plate portions 15 are connected with the hook portions byrelatively ysmall necks 16 and the free edge of each plate portion is formed with a notch 17 for engagementupon the neck of the other plate'and the edges of these necks and of the notches are correspondingly beveled,'as shown at 18 and 19, respectively, so that Vthe elements will have a dove-tailed fit.

The upper and lower edges of the plate members 15 are also preferably beveledor rounded, as shown at' 20, to avoid sharp edges. The portions of the hooks at the vsides ofthe neck 16 are likewise beveled,

as shown at 21, for conforming engagement with. the vbeveled free edges 22 of the plate portions 15 so that there will be interfitting relation of these parts so "as to brace the structure eiiiciently.

Formed integrally upon the hooks 13 are laterally extending ring members 23 designed for the passage of thethumbVv and foreinger of the operator to facilitate placing the deviceupon the nose of the calf.

In order to lock the sections 12 against casual separation, the plate portions 15 are formed with rectangular openings 24 which Vregister when the sections are assembled and which are designed to receive a hook 25,

formedupon a relatively large guard plate 26. This guard plate is preferably rounded at all its edges so as to avoid sharp corners yand may be formed with a plurality of openings 27 for the purpose of reducing its weight. This guard plate is formed cen- Y prevent the Y the guard plate 11 will swing out of the way trally of its upper portion with a rectangular opening 28 for the accommodation of the lower portion of the assembled sections 12 sov as to permit engagement of the hook within the openings 211. The upper part of this opening 28 is spanned by a rearwardly offset web 29 from the lower edge of which extends the hook 25 and it will be observed that this hook is of compound curvature so asy to provide a retaining portion which sei-.ves as more or less of af pivotfor the nose engaging sections 12. The engagement of the plate portions 15 ofthe assembled sections 12 with the web 29however, prevents swinging movement of the guard plate with respect to the nose engaging section in one direction.

The use of the device is as follows:

In the first place the guard plate 11 is dise engaged from the sections 1 2 and the sections 12 are separated. The operator then places his thumb and forcfinger through the rings 23 of the sections -12 so as to hold them properly and then inserts the knob14 with-A in the nostrils of the calf to be weaned. He

then brings the sections 12 into such position that the plate portions 15 thereof will lie against each other and helthen presses the sections together to slide these plate portions one uponV the other to engage the notches 17 over the neck portions 16. Owing to the.

beveling of the interfitting edges of these sections it will be seen that they will be held firmly against relative lateral displacement. The operator then grasps the guard plate 11, inserts the hook 25 thereof within the regis-v tering holes 211. When the device is thus placed upon an animal it will be seen that if any attempt is made to suck the guard plate 11 will be very much in the way and will calf from getting a teat within his mouth. This actionoccurs because when the sections 12 are swung into the position necessary for admitting sucking the engagement thereof with the web 29 will cause the guard plate and sections 12 to extend in :the same plane. It is, however, to be noted that if the calf desires to drink orgraze as the c guard plate curving of'the retaining portion 3() of the hook is such as to permit limited pivotal movement of the guard plate with respect to the nose engaging members.

IVhile I have shown and preferred embodiment of my invention', it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from theY spirit ofthe invention or the scope of thesubjoined claims.`

Having thus 'described my invention, I claim: i

1. A device of the character described comprising a nose engaging memberincluding a pair of slidably engaged separable sections Yformed with mating openings, and a plate carrying a hook engageable through said openings.

2.11 device of the character` described comprising a nose engaging member including a pair of slidably' associated separable sectionseacli havingA a hook portion and a ring portion, the hook portions being engageable within the nostrils of a calf and the ring portions serving as handles or finger holds, lsaid sections being formed with mating openings, and a guard plate carrying a hook lengageable through said openings. 4 I

3. A' device of the character described comp'risinga pair of similar slidably associated separable sections" each formed as a hook engageable withina nostril of an animal and each including a 'ring' portion'.

formed on the hook and further including a described the Y plate portion connectedfwith the lower end of the hook portion by a neck, the free edge of each plate portion being engaged and beveled for conforming 'engagementv with thebeveled edges ofthe other neck portion,

and said plate portions beingformed with j registering holes, in 'combination with a formed with an opening forthe Vaccommodation of saidplate` members andcarrying ahook atfsaidopening for engagement within said registering openings'.

In testimony whereof I aiiix' my si nature. .y HENRYJ. SC'HMgOLL.l
